WHEEL LOCK CONTROL: STATE-OF-THE-ART

The ability to quickly stop a vehicle under verying load and road conditions without loss of directional control obviously is important to the vehicle operator. Over the years, many improvements in braking systems have been made, but until recently, maintaining the right brake pressure for the prevailing driving and load conditions depended entirely on the skill of the driver. Now that has been changed by the development of wheel lock control systems which automatically reduce brake pressure if an impending wheel lock-up is detected. The systems modulate the brake pressure as long as the driver demands excessive brake torques. This allows more controllable and stable stops with various load and road conditions. This paper describes the current systems for preventing continuous wheel lock-up during vehicle braking. Major emphasis is placed on the wheel lock control system operation. Included is a discussion of the interaction of the wheel lock control system and the vehicle parameters to provide improved vehicle stability and control during braking maneuvers. /Author/
